and reduction of inventory. Such potential benefits, if successfully implemented, can help sustain a more effective hardwood supply chain in the U.S. and make the wood products industry more competitive. 1.2 OBJECTIVES: The overall goal of the project is to evaluate vacuum-drying technology and its economic feasibility to support the lean manufacturing of hardwood products compared to conventional drying technology. The specific objectives are: 1.1.1 To estimate conventional and vacuum drying times, quality, and costs for drying 4/4 red oak lumber 1.1.2 To determine by the use of feasibility analysis (cash flow, net present value, and internal rate of return) differences between conventional and vacuum drying for 4/4 red oak lumber 1.1.3 To determine if the high capital cost of vacuum drying equipment can be justified by the reduction of WIP and cycle time, while meeting desired throughput. 1.3 POTENTIAL OUTCOMES This research will result in the development of information for the hardwood industry about alternatives to conventional drying, which should lead to improve lead-times and reduced costs. The expected potential outcomes are the following: a) An economic feasibility analysis of conventional and vacuum-drying for 4/4 red oak lumber used for flooring manufacturing. b) A value stream map and future state map for two case studies of hardwood flooring manufacturing based on one part of their line production: 3.25” red oak pre-finished and un-finished flooring. c) A demonstration of how WIP, throughput and cycle time can be reduced in hardwood flooring manufacturing through the adoption of vacuum drying technology. 4
